Description

Technical Field

[0001] This utility model belongs to the field of powder silo arch breaking technology, specifically relating to a powder silo arch breaking device. Background Technology

[0002] Powder silos are devices used for storing and transferring powdered materials, and are widely used in various industries such as chemical, pharmaceutical, food, and energy. There are two main flow patterns for powder silos: integral flow and center flow. In an integral flow silo, all materials move towards the discharge port simultaneously during unloading; while in a center flow silo, the flow channel is mainly in the center of the silo, which may result in poor flowability of materials in the surrounding area, forming an "arched area."

[0003] In existing technologies, powder bridging within silos is a common occurrence during the storage and transport of powder materials. Common methods for breaking up powder bridging in silos include installing vibrators or air hammers on the outer wall of the silo, or installing fluidizers through openings in the silo wall. While these methods can solve the powder bridging problem, they have several drawbacks. First, they all rely on air as a power source, requiring specialized air supply equipment and increasing equipment and operating costs. Second, installation requires certain conditions on the outer wall of the silo, making the installation process complex. Furthermore, long-term use can cause wear and tear on the outer wall, affecting the silo's lifespan. This is especially problematic in small, compact silos, where these bridging devices are inconvenient to install, or even impossible, resulting in poor adaptability and practicality.

[0029] Please refer to the following: Figure 1 and Figure 2The powder silo arch-breaking device provided by this utility model will now be described. The powder silo arch-breaking device includes a silo body 10 and a vibrating feeding mechanism 20. The silo body 10 has a hollow material cavity 11, which has an inlet and an outlet located at the bottom of the cavity. The vibrating feeding mechanism 20 is disposed at the bottom of the silo body 10 and has a feeding channel communicating with the material cavity 11. The vibrating feeding mechanism 20 has an arch-breaking end that can extend into the material cavity 11. The vibrating feeding mechanism 20 is used to break up the arches in the material within the material cavity 11 through the reciprocating movement of the arch-breaking end.

[0030] By setting up a vibrating feeding mechanism 20 with an arch-breaking end that can extend into the material cavity 11, the material in the material cavity 11 can be directly arched, effectively solving the problem of material arching and ensuring smooth material feeding.

[0031] The powder silo arch-breaking device provided in this embodiment, compared with the prior art, is equipped with a silo body 10, through which powder can be stored in the material cavity 11. A vibrating feeding mechanism 20 is provided below the silo body 10, and the arch-breaking end of the vibrating feeding mechanism 20 can extend into the material cavity 11. Through the reciprocating movement of the arch-breaking end, the material in the material cavity 11 is broken up, avoiding wear on the outer wall of the silo body 10. It has low installation cost, good adaptability, and good practicality.

[0032] In some embodiments, the above-described vibratory feeding mechanism 20 may employ, as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The vibrating feeding mechanism 20 includes: a support base 21, a discharge cylinder 22, a connecting cylinder 23, an arch-breaking cylinder 24, a vibration generator 25, and an inclined plate 26. The support base 21 is located below the hopper body 10. The discharge cylinder 22 is mounted on the support base 21 and located at the bottom of the hopper body 10, and has a discharge cylinder cavity. The connecting cylinder 23 has a discharge cylinder cavity, the top of which communicates with the material cavity 11, and the bottom of which communicates with the discharge cylinder cavity 22, serving as a discharge channel. The arch-breaking cylinder 24 is located inside the connecting cylinder 23 and spaced apart from it, with its bottom integrally connected to the connecting cylinder 23 and its top extending into the material cavity 11. The vibration generator 25 is connected to the support base 21 and is poweredly connected to the discharge cylinder 22, used to drive the discharge cylinder 22, connecting cylinder 23, and arch-breaking cylinder 24 to vibrate. Inclined plate 26 is set at the bottom of arch-breaking cylinder 24 and is integrally connected with discharge cylinder 22 to guide materials.

[0033] The vibration generator 25 drives the discharge cylinder 22, connecting cylinder 23, and arch-breaking cylinder 24 to vibrate, which not only makes the material fall more easily, but also the vibration of the arch-breaking cylinder 24 can directly destroy the arch structure formed by the material, improving the arch-breaking effect. The inclined plate 26 can guide the material to enter the discharge cylinder 22 smoothly, further ensuring the smoothness of the material discharge.

[0034] Vibration generator 25, also known as a vibrator, is a device or equipment that can generate vibration by being driven by a specific power source. Vibration generator 25 is existing technology and will not be described in detail here.

[0035] In some embodiments, the connecting cylinder 23 may be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The connecting cylinder 23 is flexible.

[0036] The connecting cylinder 23 is flexible, which can better adapt to vibration, reduce the impact of vibration on the hopper body 10, and at the same time ensure the stability of the connection and extend the service life of the device. The connecting cylinder 23 can be an embedded steel wire tube, which is a flexible tube with one or more layers of steel wire embedded in the inner or outer wall of the tube, giving the tube higher strength and pressure resistance.

[0037] In some embodiments, the arch-breaking cylinder 24 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The top of the arch-breaking cylinder 24 is provided with a conical surface, which is the arch-breaking end.

[0038] The conical surface at the top of the arch-breaking cylinder 24 serves as the arch-breaking end, which can be inserted more effectively into the arch structure of the material, enhancing the arch-breaking effect and making the material fall more easily.

[0039] In some embodiments, the hopper body 10 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The hopper body 10 is provided with a connecting frame 12, which is used to support the hopper body 10.

[0040] A connecting frame 12 is provided on the silo body 10 to support the silo body 10, ensuring the stability of the silo body 10 and making the device safer and more reliable during operation.

[0041] In some embodiments, the connecting cylinder 23 may be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2The connecting cylinder 23 is detachably connected to the hopper body 10.

[0042] The connecting cylinder 23 is detachably connected to the hopper body 10, which facilitates the maintenance and cleaning of the device and improves the maintainability of the device.

[0043] In some embodiments, the arch-breaking cylinder 24 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The axis of the arch-breaking cylinder 24 is set in the vertical direction, and the axis of the connecting cylinder 23 is set collinear with the axis of the arch-breaking cylinder 24.

[0044] The collinear arrangement of the axes of the arch-breaking cylinder 24 and the connecting cylinder 23 ensures smoother material flow during descent, reduces the possibility of material blockage, and improves material discharge efficiency.

[0045] In some embodiments, the discharge cylinder 22 may be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The discharge cylinder 22 is provided with a discharge opening 221.
